The Xenomorph incorporates each new species it assimilates into the next generation of Xenomorph. Do all of the different variations of [Alien][1] Xenomorph Queens lay the same basic facehugger egg, or is each generations egg dependant on the species before it? Simply put, do the eggs evolve along with each Xenomorph version or is it a one egg laid by all scenerio?
